MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent Nol. 795,189, dated July18, 1905,

Application filed February 27, 1905. Serial No. 247.421.

To all whom/if; may concern:

.Be it known that we, ROBERT T. BELL and CHARLES H. VEITE, citizens ofthe United States, residing at Cincinnati, in the county of Hamilton andState of Ohio, have invented certain new and useful Improvements inMechanical Movements, of which the following is a specification.

Our invention relates to improvements for producing reciprocatory motionof a member simultaneously revolving about an aXis disposed at an angleto the line of such reciprocatory motion.

The object of our invention is to provide a machine of this character ofthe simplest possible construction.

Our invention consists of a shaft journaled in a suitable frame andhaving -an endless spiral groove or track and a longitudinal groove ortrack, a block mounted on the shaft to slide lengthwise thereof, a pinmounted within the block adapted to be engaged b y the spiral track, agear housed in the block adapted to be turned with the shaft by thelongitudinal track or to slide lengthwise of the shaft with the block,an additional shaft mounted in the block at an angle to its line ofmotion, a member mounted on the additional shaft adapted to be rotatedby the gear housed in the block, and means for preventing the block fromturning with the shaft.

Our invention also consists in the parts and combination and arrangementof parts as herein described.

ln the drawings, Figure l is a side elevation of our invention connectedby a chuck to a iexible shaft, a portion of which is shown. Fig. 2 is aplan of Fig. 1, excepting that a portion of the frame is broken away.Fig. 3 is a section on the line fu fu of Fig. 2. Fig. 4 is a section onthe line w lo of Fig. 2. Fig. 5 is a section on the line .fc a' of Fig.2. Fig. 6 is a longitudinal section of the block on the line y y of Eig.2 and also showing a portion of the grooved shaft, the pin, andretainingscrew and a portion of the guide-rod in elevation. Fig. 7 is alongitudinal section of the block and portions of the angularly-dsposedmembers on the line e, Fig. 1, also showing a portion of the groovedshaft and pin and portions of the angularly-disposed shafts inelevation. Fig. Sis a perspective view of the pin. Fig. 9 is anelevation of one of the angularly-disposed members. Fig. 10 is anelevation of one of the angularly-disposed shafts.

The construction of our invention is as follows, reference being had tothe drawings:

The frame 1, preferably constructed so as to form a convenient handlefor the entire machine, has the shaft 2 journaled in the bearings 3 and4 near its ends. The bearing 3 is preferably a removable one, while thebearing 4 may be adjusted to take up the wear of the shaft 2, so as toeffectively prevent end play of the latter. Also mounted in the frame 1parallel with the shaft2 is the guiderod 5. Mounted to slide on theshaft 2 and the guide 5 are the blocks 6 and 7. These blocks arerecessed to form housings for the double bevel-gears 8 and 9.respectively. The shaft 2 has a longitudinal groove or keyway 10, andthe bevel-gears 8 and 9 have feathers projecting into the groove 10, sothat the bevelgears are compelled to revolve with the shaft and may alsoslide longitudinallythereof with the blocks 6 and 7. To produce thereciprocatory motion of the blocks, the shaft 2 is provided with endlessspiral grooves 11 and 12, and the pins 13 and 14 are housed in theblocks 6 and 7, respectively, so as to bear in the endless spiralgrooves 11 and 12, respectively. These grooves are so disposed on theshaft 2 that the blocks will move in opposite directions relative toeach other. They are represented in the drawings in their' positionsnearest to each other-that is, when the pins 13 and 14 are at theadjacent reversing-points of their respective grooves.

The pin 13 or 111 is composed of the cylindrical portion 15 and widenedportion 16. The block 6 or 7 is provided with a recess 17 to receive'thewidened portion 16 of the pin and a smaller opening' 18 to receive thecylindrical portion l5 of the pin, whereby a pivotal.bearing is formedfor the pin inthe block. The recess 17 extends far enough upward intothe block to permit the pin to be raised above the opening provided forthe grooved shaft 2. After the grooved shaft 2 has been inserted throughthe openings provided for it and through the bevel-gears 8 and 9 thepins 13 and 14 may drop into their grooves in the shaft. The smalleropening 18 is threaded to receive a screw 19, which is adapted to bearon the upper end of the pin 13 or 14 and hold it in the spiral groove.

Each block 6 or 7 is provided with the studs 20, which form shafts forthe members 21 at right angles to the grooved shaft 2. The ends of themembers 21 are provided with bevel-gears meshing with the bevel-gears 8and 9, slidably mounted on the grooved shaft 2. Upon these members aremounted the cylinders 22, of any suitable material. Preferably the studs2O are braced by the yokes 23 near their outer ends.

The operation of the machine is as follows: The shaft 2 is rotated by aconvenient means, such as the flexible shaft here shown, whereupon theblocks 6 and 7 will be made to traverse the shaft by the spiral grooves.The pin 13 or 14 being oblong in cross-section where it bears in thegrooves will not change its direction at the crossing-places 24 of thegrooves, but only at the final turning-point 25, therefore the blockswill continuously and with uniform speed reciprocate and carry thebevel-gears 8 and 9 lwith them; but at the same time these bevel-gearswill be rotated because of their feathered connection with the shaft 2and will rotate the members 21 and the cylinders mounted thereon bymeans of the bevel -gears These cylinders, it is obvious, will be causedto rotate in opposite directions, so that their effect upon the movementof the machine as a whole will be m'l. Likewise the movements of theblocks 6 and 7 are opposite, so that they will not disturb theequilibrium of the machine. Obviously these features would be necessaryin a portable machine such as the one here illustrated, because theapplication of power to the machine would otherwise place it beyond thecontrol of the operator.

It will be readily seen that our machine is applicable toan extendedvariety of abradin gmachines-such as grinders, polishers, or lathes aswell as to many other kinds of machines, among which might be mentionedwinding and spinning machines.
